It will further be seen that while t c operator thus has under his control a means for preventing passengers from )assing from or into the cariiamciv, the sliiclding deviccfwhich he can beep closcd-whc has taken from him the power to bring abot conditions which will latthe passengers pass to and from the careXcept when a condition of safety is assumed'.

l-iaving described our invention, what we claim as new, and desire to secure by Letters Patent, is*- l. The combination with an elevator-car of an clectromnvnetic device located on said car, a movable dbor also mounted` on the car, an operative connection between said door and the clcctroningm'tic device by means of .whii'h thc door mnv bc opened, a door at the clwntor-lzinding, and a detachable c0nnec tion bctwecn the two doors whereby both door.` may' bc siimiltaneonsly opened by the clem,ronnignetic dc vice under predetermined coni lit ionsu i?. The combination with an elevator-car oi' nn electromagnetic device carried thereby,

car for controlling the position of said cores substantiallyY as described.

4. The combination with an elevatorcar, of an electromagnetic device thereon, a door carried upon said car, adoor at the landin means for connecting said electromagnetic device with the door carried lupon thc car, and a part mounted u on the car-door for cn- Lga ing and opening t 1e door at the landing, su stantially as described.

5. The combination with an elevator-car of a sliding door carried thereby, an electromagnetic device mounted upon the car and operatively connected with said door so as to control the same, a door at the landing normally inde endent of said electromagnetic device on tlie car, and means for connectingr the door at the landing with said elcctromagnetic device as the car moves up and down.

6. The combination with an elevator-car, of a pair of doors, a single electromagnetic device mounted upon the car, and intermedi ate mechanism between said electromagnetic device and said doors, whereby both of said doors are opened when the electromagnetic device is actuated, su bstan tiallv as described.

'r'. The combination with an clevator-car, of a solenoid carried thereon, a pair of can doors carried upon said car. a pair of cores for said solenoid, one at each end thereof, and intermediate mechanism between each of said cores, and one of said doors, whereby the doors are opened when the solenoid is energized, substantially as described.

8. The combination with an elcvat'orwar, of an electromagnetic device carried thereon, a car-door, intermediate mechanism between said car-door and said electromagnetic device so that the said door can be opened by the electromagnetic device, a door at the landing inaccessible to the operator when the car-door is closed, and a part carried upon said candoor for engaging said door at the landing, the engaging parts being constructed so that the door at the landing can be opened only when the car is in the immediate vlcinity of the landing, whereby the door at: the landing is beyond the o era tor, substantially as described.

9. he combination with an elevatorcar, of a solenoid mounted thereon at thc Vtop of the car a car-door, a pivoted lever above the head oig the car operator and having one. end

.ccnnected with said door and thc other end connected with the core of said solenoid, and a. retractin device for retractingr said core, substantial y as described.

10. The combination with an elevator-car, of an electromagnetic de vice carricd thereon, a switch carried upon said car in convenient .location to be reached by the operator, n. fdoor, also on the car, and linternicdlatc mechanism between said door and said electromagnetic device, comprising a series oi' horithe direct control of IOO XIS

the operator when the cer-doors are closed :ind n Single electromagnetic ineens carried upon the oar 'for open-ing both pairs of doors, substsintinlh 'es described.

13. The combination with im elevator-ear, of n pair ci ear-doors upon the car, e pair of doors et each landing,- tlie doors on the eer sbieding the doors on the landingso tiuit they cannot be direct-ly operated by the operator, e single electromagnetic device mounted upon the our for oponino both pair of doors,

and means whereby the ainding-doors non be opened only when the cor is in thv immediate vicinity thereof, substantially as described.

i4. The combination with un elevator-eer, of a. pir of car-doors carried upon tiievonr, n pair of doors for each landing shieided from 'the direct control of thel oporntorby the ,is in t doors on the venr, outwardly-projeeting ings or arms upon the ear-doors, inwardly-'pro footing ,lugs or portions upon the. landing'- doors, the seid car-door lues being adapted to en age the landing-door iugs when the oar lim vicinity ofthe lending,- whereby the landing-doors are opened by the opening of the car-doors 'and o singie electromagnetic. device carried upon the ear to o en said cardoors, substantially as describe( 4 15. The com bination with on' elevator-car,
